Low profile (slim)
Decent brand (Philips divx in my living room but audio sync problems with some files, and appaulingly short filename display)
Capable of playing MP3s too although thats standard.
HDD/Ethernet/Wifi are luxuries but not a must, but unlikely to be within budget
X264 compatible is another luxury I wouldn't mind on it but not needed
Good history on brand on its divx players of firmware updates would be nice.
If I wasn't so lazy I'd find a nice one on avforums but I'll take personal recommendations from HUKDers
Rep to anyone who recommends something I order ;-)
